Comparing: E 100 vs. IS-7

In June 1943, the Adlerwerke company received an order for development of the E 100. However, in 1944, heavy tank development was discontinued. By the end of the war, only the chassis was completed, which was later captured by the British Army.

Development of the IS-7 started in the spring of 1945. Prototypes successfully underwent trials in 1946 and 1947. However, the IS-7 never saw mass production.
